Question

Suppose that a laser light, positioned 100 ft from the base of a flag pole, illuminates a flag that is 85 ft above the ground.

Answer 1

Answer:

The angle of elevation is $40.36\°$

Step-by-step explanation:

Let

$\theta$ ----> the angle of elevation

we know that

The tangent of an angle is equal to divide the opposite side to the angle by the adjacent side to the angle

we have that

$tan(\theta)=\frac{85}{100}$

$\theta=arctan(\frac{85}{100})=40.36\°$
